Abstract

A vise used for holding and stabilizing a wide variety of work object shapes by means of conformable spring action jaws faces. The jaws faces are designed to be interchangeable to accommodate delicate or heavy-duty work. Dual ratchet mechanisms and a cam-driven piston provide both a quick and convenient method of closure that maintains precise and significant levels of clamping force. If desired, lockout features are included that defeat the spring action of the jaws and allows the vise to act more like a traditional vise. In addition, interchangeable smooth faced jaws allow the vise to function as a traditional vise.

Claims

1. A vise, comprising:

a base member;

a stationary jaw and a movable jaw projecting upwardly from and slidable on said base;

a linear ratchet slide mechanism connecting said stationary jaw to said movable jaw, said linear ratchet slide mechanism being adapted to allow quick movement of said movable jaw towards said stationary jaw to a point where a work object is engaged; and

a ratchet cam arrangement wherein said ratchet cam comprises a lever with a cam which engages a piston within said linear ratchet slide mechanism thereby displacing said movable jaw towards said fixed jaw.

2. The vise of claim 1, wherein said ratchet cam arrangement includes teeth that are finer than teeth contained in said linear ratchet slide mechanism.

3. The vise of claim 2, including spring loaded dogs to release the load placed on the work object by said linear ratchet slide mechanism and said ratchet cam arrangement.

4. The vise of claim 3, wherein each of said jaws contains a jaw face assembly with an array of spring loaded pins that allow the jaws to grasp work objects of a wide variety of sizes and shapes.

5. The vise of claim 4, wherein each of said stationary and movable jaws include spaced upstanding portions.

6. The vise of claim 5, wherein said linear ratchet slide mechanism includes a ratchet shaft with a slot to allow the movable jaw to incrementally slide relative to said ratchet shaft.

7. The vise of claim 5, including a U-shaped cover member having a first portion thereof adapted to be placed between each of said upstanding members of said stationary and movable jaws to thereby defeat the spring action of said spring loaded pins and a second portion thereof adapted to be placed over said spring loaded pins in order to present a smooth traditional vise surface to a work object.

8. The vise of claim 7, wherein said cover member is made of sheet metal.

9. The vise of claim 1, wherein said ratchet cam arrangement includes a cam and a cam lever, and wherein said cam is oriented in a vertical plane so that a user'"'"'s full weight can be applied to said cam lever.

10. The vise of claim 1, wherein said stationary and movable jaws have interchangeable jaw face assemblies that accommodate multiple shapes of work objects and provide a broad range of holding forces.

11. Multi-purpose vise, comprising:

a base member;

a stationary jaw and a movable jaw projecting upwardly from and slidable on said base, said stationary and movable jaws including detachable jaw face assemblies;

a linear ratchet slide mechanism connecting said stationary jaw to said movable jaw, said linear ratchet slide mechanism being adapted to allow quick movement of said movable jaw towards said stationary jaw to a point where a work object is engaged; and

a ratchet cam arrangement wherein said ratchet cam comprises a lever with a cam which engages a piston within said linear ratchet slide mechanism thereby displacing said movable jaw towards said fixed jaw.

12. The multi-purpose vise of claim 11, wherein each of said detachable jaw face assemblies contain an array of spring loaded pins that allow the jaws to grasp work objects of a wide variety of sizes and shapes.

13. The multi-purpose vise of claim 11, wherein each of said jaws contain a detachable smooth face.

14. The multi-purpose vise of claim 12, including a U-shaped cover member having a portion thereof adapted to be placed over said spring loaded pins in order to defeat the spring action of said spring loaded pins and present a smooth traditional vise surface to a work object.

15. The multi-purpose vise of claim 11, wherein said ratchet cam arrangement includes teeth that are finer than teeth contained in said linear ratchet slide mechanism.

16. The multi-purpose vise of claim 11, wherein said ratchet cam arrangement includes a cam and a cam lever, and wherein said cam is oriented in a vertical plane so that a user'"'"'s full weight can be applied to said cam lever.

17. A vise, comprising:

a base member;

a stationary jaw and a movable jaw projecting upwardly from and slidable on said base, said stationary and movable jaws each of said containing a removable jaw face assembly with an array of spring loaded pins that allow the jaws to grasp work objects of a wide variety of sizes and shapes;

a linear ratchet slide mechanism connecting said stationary jaw to said movable jaw, said linear ratchet slide mechanism being adapted to allow quick movement of said movable jaw towards said stationary jaw to a point where a work object is engaged; and

a ratchet cam arrangement wherein said ratchet cam comprises a lever with a cam which engages a piston within said linear ratchet slide mechanism thereby displacing said movable jaw towards said fixed jaw.

18. The vise of claim 17, including a U-shaped cover member having a portion thereof adapted to be placed over said spring loaded pins in order to defeat the spring action of said spring loaded pins and present a smooth traditional vise surface to a work object.

19. An interchangeable, quick release, universal jaw face assembly for holding or clamping non standard work pieces, consisting of

a jaw face;

and

wherein said jaw face is removably attached to a jaw through the use of quick-release pins that slidably pass through openings in each jaw and in each jaw face assembly.

20. The interchangeable universal jaw face assembly of claim 19 including a two-dimensional array of spring loaded pins comprising rows and columns of pins that pass through and are guided by said base plate and configured so that each pin can move independently so as to accommodate the specific shapes of non-standard work pieces.

21. A device for clamping or securing regular and irregular shaped work objects, comprising:

at least one jaw face assembly

removably attached to a jaw through the use of quick-release pins that slidably pass through openings in each jaw and in each jaw face assembly.

22. The device of claim 21, wherein said device is an accessory for a vise.

23. An accessory for a vise for clamping or securing regular and irregular shaped work objects, comprising:

at least one jaw face assembly removably attached to a jaw through the use of quick-release pins that slidably pass through openings in each jaw and in each jaw face assembly and having an array of spring loaded pins therein that allow said spring-loaded pins to conform to work objects of regular and irregular shapes when engaged.
